Product Advantages – MIL-STD-810 Blowing Wind Environmental Test Chamber
1.Standard Compliance
Fully compliant with MIL-STD-810 Method 510 for blowing dust and sand.
Ensures your equipment meets rigorous military and industrial reliability standards.
2. Robust Construction
Workroom made of SUS304 stainless steel to resist high-speed sand and dust erosion.
Double rubber sealing prevents sand and dust leakage, extending service life.
3. Precise Environmental Control
Equipped with temperature probe, wind speed probe, and concentration probe for accurate real-time monitoring.
Multi-step test cycles programmable color LCD touch screen controller, supports remote operation and data logging.
4. High-Speed Sand & Dust Simulation
Centrifugal fan system creates high-speed airflow, blowing sand/dust into the workroom.Dust/sand circulates for uniform exposure.
Air velocity for blowing dust: 1.5 – 8.9 m/s; blowing sand: 18 – 29 m/s.
5. Automatic Sand & Dust Handling
Dust inlet with stepper motor and vibration system prevents caking.
Funnel-shaped dust collection and recycling system ensures dust is reused and evenly redistributed.
Dust return port allows removal of remaining particles after the test.

Key Components and Features of MIL-STD-810 Blowing Wind Environmental Test Chamber
WorkroomSUS304 stainless steel for superior resistance against high-speed sand and dust erosion. Turntable: 1–7 r.p.m. for uniform exposure of test samples with a standard load of 50kgs. Observation Window: High-strength glass with dust-proof brush, ensuring clear visibility during testing.

Electromagnetic LockGenerates a strong suction force to tightly attract the iron plate, effectively locking the door. This lock mechanism is designed for safety purposes, preventing the door from accidentally opening during the test, which could pose risks to the operator and affect the test results.
|  |
Dust & Sand Recovery PortFunnel-shaped collection at the bottom of the chamber. Function: Dust/sand that falls is collected and filtered through a mesh sieve, then re-injected into the workroom by the centrifugal fan for continuous recycling.
|  |
ControllerProgrammable color LCD touchscreen controller. Supports 120 programs with up to 99 segments each,control wind speed, particle concentration, and temperature. Remote connectivity via Ethernet for integration with laboratory systems.Real-time logging from temperature, wind, and concentration sensors.
|  |
Pipe Cooling SystemCools high-speed airflow ducts to dissipate heat generated by friction from sand/dust in motion. water circulates around the duct creating a cooling jacket to maintain stable temperature.Prevents thermal damage to ducts caused by high-speed particle erosion.
